A Filipino student shouts anti-US slogans outside the US embassy in Manila, Philippines, 21 March 2014 in a rally condemning the docking of the USS Blue Ridge and the upcoming visit of US President Barack Obama to the country. Activists also called for an end to the presence of US troops in the country and the Visiting Forces Agreement (VFA). Obama is to visit Japan, South Korea, Malaysia and the Philippines in late April. The trip is part of his efforts to broaden US engagement in the Asia-Pacific region on all fronts, from strategic security issues to trade and diplomacy. Obama had originally planned an Asia trip for late 2013, but was forced to cancel during the budget and debt limit crisis that closed the US government for more than two weeks in October.
